cat > foo.el <<EOF
(global-set-key [C-down-mouse-1] 'foo)
(global-set-key [C-mouse-1] 'foo)
(defun foo (event)
  (interactive "e")
  (message "foo: %s" (posn-object-width-height (event-start event))))
EOF

emacs -q --no-site-file -l foo.el

load some image (say jpg, png, or tif) in image-mode,
the image needs to be large enough for the bug to occur, say 1024x768

Put mouse pointer over image.
Press C-mouse-1

emacs 24.3.93: command foo gives width and height of the image
emacs 24.4: command foo gives (0 . 0)

Strange enough: starting emacs 24.4 via

emacs -q --no-site-file --no-splash -l ~/emacs/dot/foo.el

works as expected
